LESSON 22: IR REMOTE
Introduction
In this lesson, we use the lirc library to read infrared signals returned by buttons of the remote control and translate
them to button values. When a button is pressed, the IR transmitter in the remote control will send out the
corresponding IR encoding signals. On the other side, when the IR receiver receives certain encoding signals, it will
decode them to identify which button is pressed.
Before going through this lesson make sure you followed the installation requirements we introduced at the
beginning of this document.
